Modem Workshop

A(n) (im)practical introduction to Hertzian space

It is time to descent from your Adobe cloud and descend onto the very physical Hertzian space of crystal oscillators, electromagnetic waves and solder smoke. Unlock the forgotten (im)potential of your $2000 macbook-facebook machines and reclaim the spectrum!

In this (non-AT approved, https://www.agentschaptelecom.nl/) workshop we will approach radio as a medium for (p2p) communication, power/control and (artistic) self-expression from a non-engineering point of view.

Among the topics covered are the transition from colonial radio to broadcast radio, pirate- and community radio, the utopian promise of the Web, the 'great digital switch over', modulating digital data over analog radio, encoding data into analog sound and how all of this fits in the power structures created by communication infrastructures.

Seizing the curriculum of R&D's low-end rich media publication as means of production, the participants will learn how to utilize cheap electronic components and household materials to create DIY network infrastructures, parallel to the black box modes of communications imposed on us now.

Looking beyond the usual "when the shit hits the fan" and "us versus them" scenarios, we will rather discuss the potentials, relevance and shortcomings of these DIY methodologies and how to apply it to your own practice.

ASSIGNMENT:

Apply the given technology to your own practice and make it your own, possible directions:

- Fashion (wearable radio, em detection) - Photography (radio photography? light==em waves, pcb developing) - Apps (interface radio with smartphone as alternative, parallel network) - Video art (compress video for transmission over radio waves > see: floppy films, sstv) - Architecture / sculpture / fine art (treat the Hertzian space as the physical space it really is, em-blocker) - Activism (all of the above ;), public space, debunking the myth of the aether as neutral medium) - Graphic design/illustration publication (visualize the invisible, paint by numbers image transfer, PRINTed circuit boards) - Food-design (uhf (microwave) cooking)

More directions:

- Software defined radio - hackrf, limerf, rtl-sdr dongles > gain insight on wireless payment system, the police, wifi, ip cameras? - Arduino (make a 'stupid-smart' radio) - Raspberry pi (make autonomous (smart? stupid?) pirate radio station) interface it with the web.

WHAT YOU LEARN

- Leveraging alternative technology to work - Electronics basics - DIY pcb (printed circuit boards) - Wireless communication basics - Radio basics - Modulation / demodulation - Encoding / decoding - Publish work in progress/results responsibly (git(lab))
